AIR-CONDITIONING DEVICE.

Application filed February 4, 1922. Serial No. 534,278.

T 0 all whom it may camera:

Be it known that I, BURT S. HARRISON,

a citizen of the United States of America,

and a resident of Chicago, county of Cook,

and State of Illinois, have invented a new and useful Improvement in Air-Conditioning Devices, of which the following is a specification.

This invention relates to washers or air conditioning apparatus particularly intended for conditioning air for use in ventilating for industrial purposes. An object of the invention is to provide a motor-driven spraying device for air washers, humidifiers, or dehumidifiers which does not require any special pressure developing apparatus or spray heads, piping, fittings, valves, pumps, etc. which are commonly employed in many different air conditioning apparatuses. A further object of the invention is to provide an improved rotary distributor for projecting water into a current of air; and to provide improved means for. controlling the direction and volume of the spray.

The objects of the invention are accomplished by the device shown in the accompanying drawings, in which Figure 1 is a longitudinal sectional view of an air conditioning apparatus constructed according to this invention.

Fig. 2 is a plan view ofthe same with the casing shown in section. I

Fig. 3 is an enlarged detail showing an adjustable spray controlling means.

In its general features, this air conditioning apparatus consists of a roller arranged to dip in a tank of water, and by surface contact with the water lift the same from the pan and throw it upwardly and outwardly by centrifugal force. The roller may be solid or hollow and with a surface wh1ch in some instances is plain and others grooved or corrugated or otherwise roughened in order to carry a large quantity of water on its surface. A semi-cylindrical deflector plate is adjustably mounted at one side of the roller in order to control the direction and volume of the spray. The

device is-also provided with the usual eliminators or baflies, where the mechanically entrained moisture in the air is caught and the dirt removed after the air has passed through the spray, and in a manner wellknown in connection with other types of so spray washers. These eliminators at times are arranged in either vertical or horizontal planes,-and usually have tortuous passages for the air in order to intercept the water spray.

As shown in the drawing, the spray distributing wheel or roller 1 is mounted on a shaft 2, supported by stationary bearings 3 and passing through packings 4 in the side walls of the casing 5. A motor 6 drives the roller preferably in the direction indicated in Fig. 1, when the device is used. as an air washer, but when it is employed mainly to humidify the air its arrangement and direction of rotation may be reversed in order to attain greater impact or contact with the air. The roller extends four or five inches below the water level in water pan 7, and as the roller arrives at full speed the water in the pan is drawn up b friction between the roller and the adjusta le spray plate 8. This spray plate is pivotally supported by lock nuts 9 on the rocker arms 10. The spray or rocker plate may be adjusted around its pivotal support and locked in any desired angular relation with respect to the roller, and by this means control the Width of the spray outlet 11 between the roller and the upper edge of the spray plate.

The rocker arms 10 are adjustable around the shaft 2 in order to control the tangential direction of the spray since by shifting these arms around the shaft the spray plate is swung upwardly or downwardly around the roller. The rocker arms are locked in the desired set position by the winged nuts 12 extending through the side Walls of the casing 5. Air enters the device through the inlet 13, and after it is engaged by the spray it passes through the eliminator plates 14 which serve not only to remove entrained moisture but also the dirt carried thereby. In the operation of the device, the roller 1 is driven at a normal motor speed, its surface speed, of course, being dependent upon the diameter. The force and throw of the spray varies with the surface speed of the roller, while the quantity of water sprayed varies with the area of the space between the roller and the curved spray plate 8 for any size of roller at a constant speed of rotation; The lower end of the spray plate 8 is preferably elongated so that its lower, edge will always be immersed in the water regardless of the adjustment of this plate.

Since the holes in the ears of spray or deflector plate 8 are elongated radially of the shaft the spray plate 8 may be moved to change the distance between the roller and the plate without changing the angular relation, and thereby the volume of spray delivered through the gap 11 is regulated, whereas its direction is controlled by an adjustment of rocker arms 10. By changing the angular relation of drum and deflector the nozzle effect is varied thereby effecting the static outlet pressure. 1

Although but one specific embodiment of this invention has been herein shown and described it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. In a device of the class described, a re ceptacle for fluid, and a roller rotatably mounted on a horizontal axis and partly immersed in said fluid, a plate at one side of said roller and adjustable to vary its spaced relation to the roller, the lower edge of said plate extending downwardly below the level of the fluid.

2. In a device of the class described, a receptacle for fiuid,'a roller mounted on a horizontal axis and partly immersed in said fluid, a plate at one side of said roller and adjustable to vary its angular relation with the roller, and means for adjusting said plate around the axis of the roller.

3. In a device of the class described, a receptacle for fluid, a'roller mounted on the horizontal axis and partly immersed in said fluid, said roller having a corrugated surface, a pair of arms mounted for pivotal motion around the axis of the roller, means for locking said arms in adjusted position, a curved plate supported between said arms for adjustment readily and angularly with respect to said roller, and means for lock-- in said plate in adjusted position. 4 igned at Chicago this 30th day of January, .1922.
